QUESTION 5 What are the advantages of fuel cell vehicles (FCVs) over battery-electric vehicles (BEVs)? a) Fuel cells never "die" so long as the external reactants (chemical fuel) are being fed into the fuel cell b) Fuel cell reactant tanks can be refilled much faster than charging a battery c) Fuel cells are much more efficient than batteries (in other words, it takes less energy to move the vehicle the same distance a and b are both correct a, b, and c are all correct

Explanation / Answer

A B C all are correct.

Fuel cellscan go on producing electricity by chemical reactions as long as the reactants for the reaction are continuously suppliedand hence it is said to 'not die'. Charging a battery takes more timethan filling a fuel cell with fuel .

fuel cells create electricity chemically, rather than by combustion, they are not subject to the thermodynamic laws that limit a conventional power plant. Therefore, fuel cells are more efficient in extracting energy from a fuel. Waste heat from some cells can also be harnessed, boosting system efficiency still further.
